This article is based on the idea that it is necessary to develop a quantitative method to calculate power of international actors, which will enable scholars to analyse international conflicts. The Global Potential Power Distribution Chart, which is calculated based on three main characteristics of international actors, namely population, territory and economic power, shows “potential power of states and international organisations”. It may be called “Durmuş Scale of Power (DSoP)”. The chart is a comprehensive indicator with considerable accuracy and 100 % objectivity. In this article, potential powers of international actors have been calculated for years 1987, 2004 and 2015, which gives a clear overview of the potential power distribution (balance of power) of the World regarding states and as well as international organisations. Potential military powers of some states and international organisation in year 2015 have also been calculated. This research proves by means of a contemporary approach applied and a quantitative method developed that, the World is multipolar since 2004, and China is, potentially, the most powerful state of the World since 2015. The method introduced in this article were sufficient enough to explain the effects of the enlargement of NATO and EU, EU after BREXIT, reform of the Security Council of the United Nations and instrumental enough to provide a peaceful understanding for the self-determination issue of Kosova. There are three conclusions to this research: 1) The method “Durmuş Scale of Power” is calculated is reliable because everybody with a scientific calculator or a computer can easily calculate potential power of a state provided that he or she has reliable data for territory, population and GDP. 2) “Global Potential Power Distribution Chart” is a comprehensive Chart which shows “balance of power” at a specific year. It enables us to compare power of states and international organisations in different years. 3) It is convenient to use “Durmuş Scale of Power” while analysing issues of international relations.
